Ebonised Boulle Desk with Brass and Tortoiseshell Inlay

• Ormolu - Ormolu was popular with French craftsmen in the 18th and 19th century for ornamental fittings for furniture, clocks and other decorative items. True ormolu is gilt bronze, that is bronze that has been coated with gold using a mercury amalgam. Due to the health risks associated with using mercury, this method of creating ormolu was discontinued in France in the 1830s. A substitute was developed consisting of about 75% copper and 25% zinc, however it was inferior to the bronze version. It was often lacquered to prevent it tarnishing.
• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
• Boulle - Boulle work is the name given to tortoiseshell and metal inlay using brass and sometimes silver, found on furniture and smaller wooden objects. It originated in Italy but was developed by Frenchman Andre Charles Boulle (1642 - 1732) under Louis XIV.
  
  Boulle was appointed Royal Cainet Maker to Louis XIV and designed furniture and clockcases for the monarch.
  
  In preparation, the tortoiseshell and metal were cut together following a design, using a fine fret saw.
  
  In the application of the Boulle, the carcase of piece of furniture was covered with the tortoiseshell which in turn was inlaid with the matched designs in metal, which in turn was elaborately engraved.
  
  The use of Boulle work furniture continued mainly in France until the 19th century.
• Fluting - A form of decoration found on many pieces of furniture, as well as ceramics, silver and clocks, in which round-bottomed grooves, of varying width and depth, are let into columns, pilasters, legs. As a general rule, flutes are cut in the vertical, though they may follow a turned leg in a spiral pattern. In cross-section, they may be described as a series of 'U' shapes, rising and narrowing at each end of the groove. Fluting is the opposite of reeding, with which fluting is often associated.
• Gallery - On furniture, a gallery is a small upright section, frequently pierced and decorated, around the tops of small items of furniture, such as davenports, side tables, and so forth. Galleries are made in brass or bronze,and be fretted, pierced or solid timber. A three-quarter gallery is one that surrounds three of the four sides of a table, desk or other top.
• Tortoiseshell - Tortoiseshell is a translucent material that comes from the horny carapace of a certain types of turtles, including the hawksbill turtle. It is often therefore mounted on a colour underground - often red - or inlaid with gold or silver thread, as seen in Boulle furniture.
  
  The texture and colour nuances of the material are extremely important. Heated tortoiseshell can easily be formed into various shapes. Like other natural materials, tortoiseshell becomes more beautiful with use. In a time before plastic, tortoiseshell was widely used for small objects such as combs and powder compacts.
  
  In 1973, the trade of tortoiseshell worldwide was banned under CITES (The Convention on International Trade in Endangered Species). Prior to importing or exporting items containing tortoiseshell a CITES permit must be obtained. Tortoiseshell items cannot be traded on Ebay.
  
  "Faux tortoiseshell", another case of man initiating nature, is made from old-style plastics such as celluloid and cellulos and is coloured with red, yellow and brown spots to imitate the genuine article. It is commonly used in glasses frames, musical instruments and costume jewellery.
• Ebonised - Timber that has been stained or lacquered black in imitation of ebony. The process has been used since the Renaissance, but is most commonly found in late 19th century furniture, sometimes gilded and turned in imitation of bamboo. Furniture with an ebonised finish is not currently in vogue, and this is reflected in the price for such pieces.
